17/5 x 19/10 = 323/50 or 6 and 23/50
(5/1)*(1/10)= 0.5
2 x 5 and 1/8 = 10 and 1/4
To write 820.681 in expanded form using powers of ten, you break it down into each digit's value. This can be expressed as (8 \times 10^2 + 2 \times 10^1 + 0 \times 10^0 + 6 \times 10^{-1} + 8 \times 10^{-2} + 1 \times 10^{-3}). Thus, the expanded form is (8 \times 10^2 + 2 \times 10^1 + 6 \times 10^{-1} + 8 \times 10^{-2} + 1 \times 10^{-3}).
2 over 3 divided by 3 over 5 [2/3] / [3/5] is the same as 2 times 5 over 3 times 3 [2*5] / [3*3] 10/9 1 1/9 1.111... The answer is 1 and 1/9
1/10 + 2/5 = 1/10 + 4/10 = 5/10 = 1/2
1/2 x -10 = -5
It is 2.
10
-10 x 1/2 = -5
(5/1)*(1/10)= 0.5
7/10 * 1/2 = 7/20.7/10 * 1/2 = 7/20.7/10 * 1/2 = 7/20.7/10 * 1/2 = 7/20.
2 and 1 over 10 or 2.1
No.
5/7 x 7/10 = 35/70 = 1/2 1/2 x 5/21 = 5/42
To multiply with mixed numbers:Convert the mixed numbers to improper fractionsmultiply the numerators together and the denominators togetherconvert any resulting improper fraction back to a mixed number:3/5 x 1 1/2 = 3/5 x 3/2= (3 x 3)/(5 x 2)= 9/10
2 x 5 and 1/8 = 10 and 1/4
2/5 multiply times 2(because .1=1/10). that equals 4/10 in decimal form that is .4(again, because .1=1/10).
