If A is 60% smaller than B, it means that A is 40% of B.

We can express this mathematically as:

$A = 0.40B$

Now, to find how many percent B is greater than A, we use the formula for percentage increase:

$\text{Percentage increase} = \frac{B - A}{A} \times 100$

Substituting $A = 0.40B$ into the formula:

$\text{Percentage increase} = \frac{B - 0.40B}{0.40B} \times 100$

Simplifying:

$\text{Percentage increase} = \frac{0.60B}{0.40B} \times 100 = 1.5 \times 100 = 150\%$

So, B is 150% greater than A.

Tip: When calculating percentage increase or decrease, always compare the difference relative to the initial value.
