Estimate using rate per 100. 24% of 289

sdas [7]

Estimate using rate per 100. 24% of 289

Solution: We have to find the 24% of 289,

We know that:

$24\%=\frac{24}{100}$

$\therefore 24\% of 289 = \frac{24}{100} of 289$

$=\frac{24}{100}\times289$

$=0.24 \times 289$

$=69.36$

$\therefore 24\% of 289 = 69.36$
