9/10 - 2/5 = In order to add or subtract fractions, they must have the same denominator. 9/10 - (2/2)(2/5) = 9/10 - 4/10 = 5/10 = 1/2
the answer is -6
2/3 multiplied by 9/1
2 over 3 plus 5 over 9 equals 11 over 9 or 1 and 2 ninths.
(2/9) * (8/9) = (2*8) / (9*9) = 16/81 and: 2/9*8/9 = 16/81 2/(9*8)/9 = 1/324 2/(9*8/9) = 1/4 it depends on where you put the brackets
1 over 10
2/3 - 3 = 2/3 - 3/1 = 2/3 - (3×3)/(1×3) = 2/3 - 9/3 = (2-9)/3 = -7/3 = -(2×3+1)/3 = -2 1/3
9/10 - 2/5 = In order to add or subtract fractions, they must have the same denominator. 9/10 - (2/2)(2/5) = 9/10 - 4/10 = 5/10 = 1/2
1/2 + 1/9 = 9/18 + 2/18 = 11/18
2/9 to 1/3 2/9 is smaller than 1/3 = 3/9
1/9 + 1/2 is 11/18
1/9 = 1/9 2/6 = 3/9 2/3 = 6/9
1/3 = 3/9 + 2/9 = 5/9
1/2 − 5/9 = -1/18
the reciprocal of 2 over 9 is 9 over 2
1 and 7 over 9
16 over 9 or 1 and 7 over 9.
