hi, I'm not good at explaining things...please help. In your own words describe how to find the least common denominator for these fractions, 3/7 , 4/5

LCD of 7 and 5 is 35

Step-by-step explanation:

In many cases, you can find the lowest common denominator by simply multiplying the two numbers together. This method works in your example.

7 x 5 = 35

The two fractions would become 15/35 and 28/35

There will be times when this will not get you straight to the answer, eg find the lowest common denominator of 8 and 12. For this you need to list some multiples of the numbers until you get a number which appears in both lists:

8: 8, 16, 24

12: 12, 24

So, the lowest common denominator of 8 and 12 is 24.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
