- 0.172
- 17.2
- 1.72
- None of these
Explanation
2994 ÷ 14.5 = 172
We can cross-multiply to get:
2994 × 14.5 = 172 × 100 (multiplying both sides by 100)
Then, we can convert the percentages to decimals by multiplying both sides by 0.01:
29.94 × 145 = 1720
Finally, we can divide both sides by 100 to get:
29.94 × 1.45 = 1720 ÷ 100
= 17.2
