➙ Find a number whose 80% is 528 .

$\color{lime}\underline{\underline{\color{red}{\bf{Answer:}}}}$

➙ Let the number be 'x'

᠉ 80% of x is 528

᠉ $\bf\frac{80}{100}$ × x = 528

᠉ $\bf\frac{4}{5}$ × x = 528

᠉ 4x = 528 × 5

᠉ 4x = 2640

᠉ x = $\bf\frac{2640}{4}$

᠉ x = 660

$\color{lime}\boxed{\boxed{\color{red}{\mathtt{80percent\:of\:660\:is\:528}}}}$

Answer 2

Step-by-step explanation:

Percent (%)' means 'out of one hundred':

80% = 80 'out of one hundred',

p% is read p 'percent',

80% = 80/100 = 80 ÷ 100.

Calculate percentage:

'Percentage' is obtained by multiplying 528 by 80%.

80% × 528 =

(80 ÷ 100) × 528 =

(80 × 528) ÷ 100 =

42,240 ÷ 100 =

422.4;
