![1\frac{7}{9} =\frac{16}{9} =[\frac{4}{3}] ^{2}](https://tex.z-dn.net/?f=1%5Cfrac%7B7%7D%7B9%7D%20%3D%5Cfrac%7B16%7D%7B9%7D%20%3D%5B%5Cfrac%7B4%7D%7B3%7D%5D%20%5E%7B2%7D)
Step-by-step explanation:
For this case we can make the following rule of three:
21 ------> 70%
x --------> 100%
Clearing x we have:
x = (100/70) * (21)
Rewriting we have:
x = (10/7) * (21)
x = 30
Thus,
21 is 70% of 30
Answer:
21 is 70% of 30
Answer:
$13.50
Step-by-step explanation:
First, we got to multiply $18 by 25% or .25
