d. 50% of 90 is ______
e. 10% of ______ is 7
f. 30% of 70 is ______

Explanation:

Step1: Convert % to decimal, multiply

$20\% = 0.2$, $0.2 \times 60 = 12$

Step2: Divide by decimal %

$25\% = 0.25$, $\frac{6}{0.25} = 24$

Step3: Divide part by whole, ×100

$\frac{14}{100} \times 100 = 14$

Step4: Convert % to decimal, multiply

$50\% = 0.5$, $0.5 \times 90 = 45$

Step5: Divide by decimal %

$10\% = 0.1$, $\frac{7}{0.1} = 70$

Step6: Convert % to decimal, multiply

$30\% = 0.3$, $0.3 \times 70 = 21$

Answer:

a. 12
b. 24
c. 14
d. 45
e. 70
