You multiply the two fractions. To multiply two fractions, the numerator of the result is the product of the numerators, and the denominator of the result is the product of the denominators.
The answer is 7.To find seven tenths, you first divide 10 by 10 and then multiply your answer by 7.
7/10 - 1/5 = 7/10 - 2/10 = 5/10 = 1/2
10 tenths
42. You have to find one tenth of 60, by dividing it by 10, which gives you 6. You then times this by how many tenths you need, in this case, 7. So, you multiply 6 x 7= 42.
The number after the decimal.
2.3 + 8.9 = 11.2
7/10 is the same as 70/100, so the total is (70+15)/100=85/100.
Multiply it by 0.3
The answer is 17. To find this, you look at the tenths column which is 7. If the tenths is 0-4 you round down. If the tenths is 5-9 you round up.
Divide by thirteen.
Ten tenths equal 1. So to find half of that, devide both sides by 2; you end up with 5 tenths equal one half.
Go find one then.
