Answer:

We just have to make the ratio into a fraction and simplify:

$21:35=\frac{21}{35}=\frac{3}{5}$

$12:15=\frac{12}{15} =\frac{4}{5}$

$8:20=\frac{8}{20}=\frac{2}{5}$

$2:10=\frac{2}{10} =\frac{1}{5}$

Can you do it step by step for me

liraira [26]

Answer:

= 10

Step-by-step explanation:

$r + (s+1)^{2}$ ÷ $3$

if, r = 7 and s = 2

SO..

$7 + (2+1)^{2}$ ÷ $3$

Add 2 and 1 to get 3.

$7 + \frac{3^{2} }{3}$

Calculate 3 to the power of 2 and get 9.

$7 + \frac{9}{3}$

Divide 9 by 3 to get 3.

7 + 3 = 10
