639.497 rounded to the nearest tenth

1 answer:

7 0

It is 639.5. this is how you round numbers to the nearest tenth:

if the digit in the hundredths place is 5 or more you round up one, if it is lower than 5 it stays the same, pay no attention to the thousandths place....ex--> 0.497
the 4 is the tenths place
th 9 is the hundredths place
the 7 is the thousandths place......since 9 is 5 or more you round the 4 up one number, so the 4 would be a 5. pay no attention to the 7. lets do another

0.426
the 4 stays as a 4 because 2 is a lower number than 5.

there are 48 students in a school play. the ratio of boys to girls is 5:7. how many more girls than boys are in the school play?

Alex Ar [27]

We can use trial or error method here...

If we take 4 table, 4*5 = 20 and 4*7 = 28. 20+28 = 48.
20 : 28 = 5 : 7

So, there are 20 boys and 28 girls in a school play and there are 8 girls more than boys.

If you look over tables and try it out, only 4 table works for the given ratio.
