Now it is given that 2/3 of a number is 10

By the given condition

$\displaystyle \sf \frac{2}{3} \times n = 10$

Step 2 of 3 :

Find the number

$\displaystyle \sf \frac{2}{3} \times n = 10$

$\displaystyle \sf{ \implies }n = 10 \times \frac{3}{2}$

$\displaystyle \sf{ \implies }n = 15$

Step 3 of 3 :

Calculate 1.5 times that number

1.5 times that number
