1 4/5 x 1 1/3 x 1 3/4=720/48
then I get 15 not sure it that is correct?
1 4/5 = 9/5
1 1/3 = 4/3
1 3/4 = 7/4
multiply it all together and you have
9/5 * 4/3 * 7/4 = 9*4*7 / 5*3*4
9 i 3*3, so you can cancel out 3*4 in both top and bottom, leaving you with
3*7 / 5 = 21/5
How ever did you get 15?
good question? I just did it again and came up with the answer you did.
Thank you Steve
To multiply mixed numbers, we first need to convert them into improper fractions. Then, we can multiply the fractions together and simplify if necessary.
Let's convert the mixed numbers into improper fractions:
1 4/5 = (1 * 5 + 4) / 5 = 9/5
1 1/3 = (1 * 3 + 1) / 3 = 4/3
1 3/4 = (1 * 4 + 3) / 4 = 7/4
Now, we can multiply the fractions:
(9/5) * (4/3) * (7/4)
To multiply fractions, multiply the numerators together and the denominators together:
(9 * 4 * 7) / (5 * 3 * 4)
Simplifying the numerator and denominator:
(252) / (60)
The next step is to reduce the fraction to its simplest form. Both the numerator and denominator are divisible by 4, so we can divide both by 4:
(252 ÷ 4) / (60 ÷ 4)
63/15
So, the final result is 63/15.
However, you mentioned that the answer you calculated was 15. This seems like an incorrect answer. It's possible that you made an error during the calculation. Please double-check your work, starting from the conversion of the mixed numbers into improper fractions and the subsequent multiplication steps.
