To find the number we do the inverse of division, and that's multiplication. We multiply 8 x 5 x 3 to get 120, that's our number. So Fernando is thinking of the number 120, and we can prove that it's correct by dividing 120 / 3 then the result divide it by 5 and we get 8.

Simple, if you have the ending number as 8;

You divided it by 5. So go in reverse, and multiply by 5.

8*5=40

Then, do the same thing again, you divided it by 3, so multiply by 3.

40*3=120.

Thus, the number that Fernando gave to Maria is 120.

To find the product of 42.12 and 10³, move the decimal point in 42.12 __ places to the right because 10³ has __ zeros.
Yakvenalex [24]
<h3>To find the product of 42.12 and 10^3,  move the decimal point in 42.12 3 places to the right because 10^3 has 3 zeros</h3>

<em><u>Solution:</u></em>

Given that,

\text{ product of } 42.12 \text{ and } 10^3

Which means,

42.12 \times 10^3

Here, the exponent of 10 is positive ( which is 3)

When the exponent is positive, we have to move the decimal point to right

When you multiply a number by a power of 10, ( 10!, 10^2, and so on ) move the decimal point of the number to the right the same number of places as the number of zeros in the power of 10

Here, exponent is 3 , therefore move the decimal point right 3 places in 42.12

Therefore,

42.12 \times 10^3 = 42120
