See they have given that 3×(-4) so by the method of integer of multiplication we have to solve it : 1. We have to multiply 3 by 4 =3 × 4 = 12 2. After we solve it; we should not forget the - sign. So now put the minus sign to 12 ; therefore -12 From first : = 3 × (-4) = 3 × 4 = 12 = -12 Because of - sign So that 's your solution Might by you have understood my integer method Bye

Sia ? 6 years, 2 months ago

A ratio between two or more quantities is a way of measuring their sizes compared to each other. The first term of a ratio is called antecedent and the second term is called consequent. This type of ratio has no units. If different quantities are compared, this special type of ratio is called a rate and it has units.

How to find per cent

Posted by Asok Kumar 6 years, 2 months ago

Sia ? 6 years, 2 months ago

The math to determine a percentage is to divide the numerator (the number on top of the fraction) by the denominator (the number on the bottom of the fraction), then multiply the answer by 100. For example, the fraction 6/12 turns into a decimal like this: 6 divided by 12 (which equals .5) times 100 equals 50 percent.
