Question

Enter the unknown value that makes this statement true. 40% of blank is 128

Answer 1

320

Explanation:

40% of blank is 128

40% = 0.4

0.4x = 128

divide both sides by 0.4:

0.4x/0.4 = 128/0.4

x = 320

Answer 2

40% of 320 is 128.

Explanation:

Forming the equation,

→ (x/100) × 40 = 128

Now the value of x will be,

→ (x/100) × 40 = 128

→ (40x/100) = 128

→ 2x/5 = 128

→ 2x = 128 × 5

→ x = 640/2

→ [ x = 320 ]

Hence, the answer is 320.
