Question

Using appropriate properties find 3 upon 5 into minus 3 upon 7 minus 1 upon 14 + 3 upon 5 into 1 upon 7

Answer 1

Answer: -17/70

Step-by-step explanation:

3/5 × (-3/7) -1/14+ 3/5 × 1/7

Combining 1st and 3rd term,

= [3/5 × (-3/7) + 3/5 × 1/7] - 1/14

= 3/5 × [ -3/7 +1/7] -1/14, [by distributive property]

= 3/5 [(-3+1) /7] - 1/14

= 3/5 × (-2) /7 - 1/14

= -6/35 - 1/14 , taking LCM (35, 14) = 70

= [ -6×2 - 5×1]/70

= (-12-5) /70

= -17/70
