Answer:
27 cm
Step-by-step explanation:
So the ratio you have is
width(x) : length (36)= 3:4
Divide 36 (length) by the ratio length. 36÷4=9
They are multiples of nine, so multiply the width by 9 to get the 3.
3×9=27
You have 27:36
If you want to check it, divide both by 9 and you get 3:4
Answer:
5) 1.5 : 7
Step-by-step explanation:
I think for 4) you need only one ratio, for example
The ratio of lemon to sugar is
1 : 1,5
This is the same lik 2:3, or any other you wrote. So it is enough to write just one ratio.
5) also one ratio is enough, becuse all other are the same.
The ratio of cups od sugar to cups of water is 1.5 : 7.
-19 - 7 = 5x - 3x
-26 = 2x
2x= -26
x= -26/2
x= -13
