So what you can do is lets say you have to multiply 5/6 by 3 you just make 3 into a mixed number 2 6/6 and multiply it like that.
Add 9 because -2 to 7 equals 9 hope this helped
Answer:
100 red bricks
Step-by-step explanation:
Let's say red bricks is equal to 5x
Gray bricks is equal to 2x
We have an equation
2x + 5x = 140
= 7x = 140
Divide through by 7 to get the value of x
X = 140/7
X = 20
Red bricks = 5(x)
= 5(20)
= 100
Gray bricks = 2(x)
= 2(20)
= 40
Therefore in conclusion the number of red bricks is 100.
The answer is 64 boys are in the soccer league.
X/160 = 40/100
X/160 * 100 = 40/100 * 100
5x/8 = 40
(8 * 5x)/8 = 40 * 8
5x = 320
5x/5 = 320/5
x = 64
