Can someone help me dividing fractions: 2/10%1/2 with procces

Answers

Answer 1
Answer: First off, 2/10 can be simplified. 2 divided by 2 is 1. So the numerator is 1. 10divided by 2 is 5. Denominator is 5. So right now your first fraction is 2/5. 2/5 divided by 1/2. First, you keep your first fraction. You switch the division sign to multiplication, and always do the reciprocal (flip it around) of the second fraction. So instead of 1/2, it would be 2/1. Then multiply. 2/5 x 2/1. 2x2 is 4, 5x1 is 5. 4- numerator/5-denominator. Your answer is 4/5.

the length of a rectangle is 5 less than 3 times the width. the perimeter is 150 centimeters. what is the length and width?

Answers

The lenght: x
The width: y
x = 3y-5 (cm)
x + y = 150/2 = 75 (cm)
=> 3y-5+y = 75
=> 4y = 80
=> y = 20 (cm)
=> x = 3×20-5 = 55 (cm)
