How do you write 8 21/40 as a decimal

Mathematics

Anna [14]3 years ago

<span>to write 8 21/40 as a decimal we need to write the fraction where denominator is a power of 10.
the denominator now is 40, when we multiply 40 by 25, we get 1000.
then the denominator would be a power of 10.
                                                                     
lets multiply the fraction 21/40 by 25 </span>\frac{21*25}{40*25} =  \frac{525}{1000}
<span> 8 21/40 is a mixed fraction made of 8 wholes and a fraction that is now 525/1000.
                                                                   
when dividing by 1000, the decimal point that is after 525 should move 3 decimal places to the left, then the decimal point comes before 525.
then 21/40 is equal to 0.525. since we have 8 wholes;                                                                     8 + 0.525 = 8.525</span>

In 1934 there was an extreme drought and the Great Plains and the number 1,934 is the value of the nine and the hundredth place
WARRIOR [948]

It should be noted that No. the value of the 9 in the hundred place is not ten times the value of 3 in the tens place.

<h3>How to illustrate the information?</h3>

It should be noted that the value of 3 in 1934 is 30 and the value of 9 is 900.

1934 = 1000 + 900 + 30 + 4

Therefore the value of 9 will be:

= 30 × 3

Therefore, the the value of the 9 in the hundred place is 30 times the value of 3 in the tens place.
