Please explain step by step for 0.67÷0.3=?
pentagon [3]
Multiply each of the numbers by a ten to a power that they both become whole numbers.

0.67 * 10^2 = 67
0.3 * 10^2 = 30

Divide as usual.

67 / 30 = 2 \frac{1}{3}

So, the answer is 2 1/3.

Answer:

StartFraction g Over 6 EndFraction = 16; g = 96

Step-by-step explanation:

The quotient of a number and six is sixteen.

A quotient is a result obtained by dividing one quantity by another.

Thus, we have g to be the unknown number = g / 6 = 16

Thus, g = 16*6 = 96.
