Answer 2

Answer:

x=70

Step-by-step explanation:

$60\% \: of \: x = 42 \\ \\ \frac{60}{100} \times x = 42 \\ \\ \frac{3}{5} \times x = 42 \\ \\ \frac{3x}{5} = 42 \\ \\ 3x = 42 \times 5 \\ \\ x = \frac{42 \times 5}{3 } \\ \\ x = 14 \times 5 \\ \\ x = 70$

60/100 can be simplified by dividing it by 20

20×3=60

20×5=100

so 3/5 common

in next step 42/3=14 that's why 14×3
