Note: The resulting fraction is in the reduced form. A reduced fraction is a common fraction in its simplest possible form. This calculator does not provide result in 310 times 2/9 is equal to 1/15 in fraction and 0.0667 in decimal form. 3/10 times 2/9 in fraction form: 3/10 x 2/9 = ? Arrange the fractions in the product expression form as like the below: = 3/10 x 2/9. = (3 x 2)/ (10 x 9) Check the numerator and denominator and cancel if anything cancelled each other: = 1/15. 3/10 x 2/9 = 1/15. 13 x 2/7 = 2/21. 1/3 times 2/7 is equal to 2/21 in fraction and 0.0952 in decimal form. 1/3 times 2/7 in fraction form: 1/3 x 2/7 = ? Arrange the fractions in the product expression form as like the below: = 1/3 x 2/7. = (1 x 2)/ (3 x 7) Check the numerator and denominator and cancel if anything cancelled each other: = 2/21.
Lets set up 2/3 and 5/6 side by side so they are easier to see: 2 3 x 5 6. The next step is to multiply the numerators on the top line and the denominators on the bottom line: 2 x 5 3 x 6. From there, we can perform the multiplication to get the resulting fraction: 2 x 5 3 x 6 = 10 18. You're done! You now know exactly how to calculate 2/3 x 5/6.
Weare allowed to do this since the exponent is an odd number. We can use this rule to move the exponent into the fraction: ( a b)x = ( ax bx) This gives us −( 2−3 3−3) Then we use a rule for negative exponents: a−x = 1 ax. Because of the rule above, we can move 2−3 down, and 3−3 up; −(33 23)
