Charles bought 7/8 foot of electrical wire and 5/6 foot of copper wire for his science project .What is the least common denomin
coldgirl [10]

Answer:

The least common denominator of the fractions is 24

Step-by-step explanation:

we know that

The <u>least common denominator</u> (LCD) is the smallest number that can be a common denominator for a set of fractions

so

we have

7/8

Multiples of 8 -------> 8,16,24,32,...

5/6

Multiples of 6 -------> 6,12,18,24,...

24 is a common multiple of 6 and 8.  It is their lowest common multiple

<em>Alternative Method</em>

we have

8=2^{3}

6=2*3

The least common multiple are those common and non-common numbers with the greatest exponent

so

lcm= 2^{3}*3=24

A recipe for cookies calls for 3 1/4 cups of sugar. Amy has already put in 3 1/9 cups. How many more cups does she need to put i
sammy [17]
So 3 and 1/4 is equal to 4/4+4/4+4/4+1/4=13/4

so she put in 3 and 1/9 or 9/9+9/9+9/9+1/9 or 28/9

28/9+x=13/4
13/4-28/9=x

so we convert so that the bottom numbers are the same

a short cut is 3 and 1/4+x=3 and 1/9 
3 1/9+x=3 1/4
subtract 3 from both sides
1/9+x=1/4
subtract 1/4 from both sides
x=1/4-1/9
convert bottom number to same thing
1/9=4/36
1/4=9/36
x=9/36-4/36
x=5/36
5/36 cups
