soldier1979 [14.2K]

37 is 25% of 148; 148 is 400% of 37

Step-by-step explanation:

Let us solve the questions one by one

"37 is ____ % of 148"

Let x be the percentage

Then

$37 = x\%\ of\ 148\\37 = 148x\\x = \frac{37}{148}\\x = 0.25$

to convert in percentage, multiplying by 100

= 25%

"148 is ____ % of 37"

Let y be the percentage

then

$148 = y\%\ of\ 37\\148 = 37y\\y = \frac{148}{37}\\y = 4$

To convert into percentage, multiplying by 100

= 400%

Hence,

37 is 25% of 148; 148 is 400% of 37
