Sagot :
Convert the fractions so they both have the same denominator (bottom part of the fraction)
1/5 = 7/35
This is because 5*7=35, so 1*7=7
1/7 = 5/35
This is because 7*5=35, so 1*5 =5
Then subtract the top numbers to get the answer:
[tex] \frac{7}{35}-\frac{5}{35} = \frac{2}{35} [/tex]
1/5 = 7/35
This is because 5*7=35, so 1*7=7
1/7 = 5/35
This is because 7*5=35, so 1*5 =5
Then subtract the top numbers to get the answer:
[tex] \frac{7}{35}-\frac{5}{35} = \frac{2}{35} [/tex]
First you have to make your denominators the same. You have 5 and 7 as your denominators. 5 x 7 = 35 So we can use 35 as the common denominator. So you have
1/5 = 7/35
1/7 = 5/35 now you can subtract
2/35
Hope that I was able to help you. :-)
