A decrease of 2% means only 98% of the original value lasts. Therefore Hal should multiply with 98%

To convert percentages to decimals, one has to divide by 100, and therefore
98% = 98/100 = 0.98.

Hence, Hal should multiply with 0.98.

The largest frog in the world is the goliath,found in west africa. It can grow to be 12 inches long. The smalest in the world is
denis23 [38]

Answer:

4.8 inches

Step-by-step explanation:

Given: The largest frog in the world is goliath which is 12 inches long.

           The smallest frog is about 2.5 as long as the goliath.

Lets assume the length of smallest frog be "x".

As given, smallest frog is about 2.5 as long as the goliath.

∴ we can form equation as 2.5x= 12\ inches

Solving the equation to find the value of x

2.5x= 12

Dividing both side by 2.5

⇒ x= \frac{12}{2.5}

∴ x= 4.8\ inches

Hence, the length of smallest frog is 4.8 inches.
