Answer:
59/40
Step-by-step explanation:
.5+3/5+3/8=1.475
1.475=1475/1000
1475/25 1000/25 = 59/40 or 1 19/40 as a mixed number
Answer:
[tex]\frac{59}{40}[/tex]
Step-by-step explanation:
One half of a number can be written as [tex]\frac{1}{2}[/tex]
three fifth of a number can be written as [tex]\frac{3}{5}[/tex]
three eighth of a number can be written as [tex]\frac{3}{8}[/tex]
We have to find the sum of all three
which is
Sum = [tex]\frac{1}{2}+\frac{3}{5}+\frac{3}{8}[/tex]
No we have to make the denominator same for this we have to find the LCM of 2,5,8
Factors of 2 = 2
Factors of 5= 5
Factors of 8 = 2 * 2 * 2
LCM = 2 * 5 * 2 * 2
=40
Multiplying and dividing Every term with 40 for making the denominator same
Sum = [tex]\frac{40*1}{2*40}+\frac{3*40}{5*40}+\frac{3*40}{8*40}[/tex]
Cancelling out the terms
Sum = [tex]\frac{20*1}{40}+\frac{3*8}{40}+\frac{3*5}{40}[/tex]
Sum = [tex]\frac{20}{40}+\frac{24}{40}+\frac{15}{40}[/tex]
Adding the terms of numerator
Sum = [tex]\frac{20+24+15}{40}[/tex]
Sum = [tex]\frac{59}{40}[/tex] this is the answer of the required
