See it is a very simple question just give your logic and get the magic. 1. take l.cm of 2 and 3 which is 6 2. multiply 6 with 'm', m-1/2, with positive 1 and with -m-2/3 3. After that you should get 6m-3m+3=6-2m+4 4. 3m+3=10-2m 5.3m-2m=10-3 6. 5m=7 m= 7/5 Hope this will help you, thank you From Sourish Das to Reshav Dubey

Answer: 2√2 : 1 Step-by-step explanation: Refer the attached figure In rectangle ABCD AB is the longer side BC is the smaller side AC is the diagonal ΔABC is the right angled triangle since all angles of rectangle is of 90°. Let the smaller side BC be x Diagonal = AC = So, In ΔABC Thus the longer side is Smaller side = x Ratio of its Sides = Longer side : smaller side = 2√2x : x = 2√2 : 1 Hence ratio of its sides is 2√2 : 1 .

Find the smallest number by which 2560 must be multiplied so that the product is a perfect cube

Posted by Vansh Chawla 5 years, 6 months ago

2 answers

Sneha Ramparia 5 years, 6 months ago

2560=2×2×2×2×2×2×2×2×2×5 =2 3 ×2 3 ×2 3 ×5. ∴2 3 ×2 3 ×2 3 ×5(5×5) is a perfect cube. So we should multiply 2560 by (5×5)=25 to make it a perfect cube.

Sneha Ramparia 5 years, 6 months ago

Smallest number to be multiplied is 5^{2}=25 Step-by-step explanation: Factorization is the process of simplifying the number based on its factors or divisors. Now, we need to find the smallest number by applying the factorization to the given number. Now, by factorizing the given number, we get, \therefore 2560=2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 5=2^{9} \times 5 The nearest perfect cube is obtained by multiplying 2^{9} \text { and } 5^{3} Therefore, the nearest perfect cube of 2^{9} \times 5=2^{9} \times 5^{3} Hence, the smallest number to be multiplied is 5^{2}=25

Hukma Ram Saran 5 years, 6 months ago

Human resources describes the people who make up the workforce of an organization, industry, business sector, or economy. "Human capital" is sometimes used synonymously with "human resources", although human capital typically refers to a narrower effect.

Yogita Ingle 5 years, 6 months ago

The term human resources refers to the size of the population of a country along with its efficiency, educational qualities, productivity, organisational abilities and farsightedness. It is the ultimate resource, but not equally distributed over the world. Human Resources differ in their educational levels, age and ***. Their numbers and characteristics also keep changing.

How to Represent number on the number line

Posted by Shraddha Menti 5 years, 6 months ago

CBSE > Class 08 > Mathematics

2 answers

Sneha Ramparia 5 years, 6 months ago

II. Improper fractions: We know that improper fractions are those in which numerator of the fraction will be greater than its denominator. Since, the numerator is greater than the denominator the number will be greater than one. To, represent such rational fractions on the number line first we convert the improper fraction into the mixed fraction so as to know between which integers will the fraction lie. Ex:-Represent 95 on the number line. Solution: Since the given fraction is an improper fraction and is positive. So, it will lie on the right side of the number line. Let us first convert the given rational fraction into mixed fraction to find between which whole numbers the fraction exists on the number line. The mixed fraction conversion of the rational fraction will be 1 45.,which means that the fraction would be between 1 and 2 at 45 point. To do so first we’ll divide number line between 1 and 2 into 5 equal parts and then the fourth part of 5 parts will be the required rational number on the number line.

Sneha Ramparia 5 years, 6 months ago

Proper fraction: We know that proper fractions are those in which numerator is less than the denominator. Such fractions exist between only zero and on. Proper fractions are less than one and greater than zero. So, proper fractions always exist between zero and one on number line Ex:-. Represent 45 on the number line. Solution: As we know that 45 is a positive and that too proper fraction, so it will lie at the right side of the zero and will be less than 1. To do so first we will divide number line between zero and one into 5 equal parts. 45will be the fourth part of five equal parts.
