Answer:
N = 3/8
Step-by-step explanation:
let the number be N
let's express the word sentence as a mathematical expression:
"a number multiplied by 2/5"
= "N" multiplied by 2/5
= N x (2/5)
= (2N/5) ------- (1)
"a number multiplied by 2/5 is 3/20" can be written as:
(2N/5) = 3/20 (multiplying both sides by 5)
2N = (3/20) x 5
2N = 3/4 (divide both sides by 2)
N = (3/4) ÷ 2
N = (3/4) x (1/2)
N = 3/8

Answer:
10%
Step-by-step explanation:
We have procent:
520 —-> 100%
572 ——> x%
So, it is:
520*x=572*100
X=57200/520=110%
110%-100%=10%
Start at 5 and go up 3 and move 4 to the right
