Answer:
1/12
Step-by-step explanation:
3/4=9/12
12/12-9/12=3/12
(3/12)/3=1/12
The least common multiple (LCM) of a set of numbers is the lowest value that all of the numbers can be divided by and have a result of a whole number.
In this case, the least common multiple is 21 because 21/7=3 and 21/21=1.
Total units would be: 3+4 = 7
value of 1 unit = 28/7 = 4
ratio would be 3(4) & 4(4) = 12 & 16
40.8 ÷ 69.9 = 0.5836909871
58%
