Question

7/10+2/5+3/2 answer me as step by step​

Answer 1

Step-by-step explanation:

find lcm first

7/10,

2/5×2/2=4/10

3/2×5/5 = 15/10

7/10+4/10+15/10

= 26/10

= 13/5

Answer 2

Step-by-step explanation:

=7/10+2/5+3/2

Take the L.C.M of the denominators and multiply the numerator with the number that is required for it's denominator to become the L.C.M

Here the L.C.M will be 10.

Therefore it is required for 5 to be multiplied with 2 and 2 to be multiplied with 5 to become 10.

Therefore multiply the second fraction by 2/2 and the third with 5/5.

This then becomes

=7/10+(2/5)(2/2)+(3/2)(5/5)

=7/10+4/10+15/10

Now that the denominators of all the fractions are same, we will add the numerators.

=(7+4+15)/10

=26/10

=2.6
