Question

subtract the sum of -3/7 and 5/14 from the sum of-3 and 7/10​
please step by step

Answer 1

Step-by-step explanation:

-3/7 + 5/14 = -1/14

-3 + 7/10 = -23/10

-23/10 - (- 1 )/14

-156/70 = -78/35

Answer 2

Answer:

-156/70

Step-by-step explanation:

sum of -3/7 and 5/14

= -3*2/7*2 + 5/14

= -6/14 + 5/14

= -1/14

sum of -3 and 7/10

= -3*10/1*10 + 7/10

= -30/10 + 7/10

= -23/10

subtracting -1/14 from -23/10

= -23/10 - -1/14

= -23/10 + 1/14

LCM of 10 and 14 = 70

-23*7/10*7 + 1*5/14*5

= (-161 + 5)/70

= -156/5
