15% of a number is 45
15% × x = 45
x = 45 ÷ 15%
x = 45 ÷ 15/100
x = 45 × 100/15
x = 4500/15
x = 300

Check:
15% × 300
= 15/100 × 300
= 15 × 3
= 45

45 is 15% of 300.

45 = 15% of number
45 = 15% × n
15% = [tex] \frac{15}{100} [/tex] = 0.15

45 = 0.15n

[tex] \frac{45}{0.15} [/tex] = [tex] \frac{0.15n}{0.15} [/tex]
0.15 and 0.15 cancels out

300 = n

15% of 300 is 45

45 is 155 of 300
