Answer :

100 --> 210
a --> 147
so 210a=100 x 147, so a=70

the number that 210% of it equals 147 is 70.

The student asked: 210% of what number is 147? To find the answer, we set up the equation: 2.10 imes x = 147, where x is the number we are looking to find.

Next, we divide both sides of the equation by 2.10 to solve for x:

2.10 × x / 2.10 = 147 / 2.10x = 70

Therefore, the number that 210% of it equals 147 is 70.
