3. Using appropriate properties find,
2/5 ×(-3)/7 -1/( 14) - 3/7 × 3/5

4. The sum of two rational numbers is (-3)/5, if one of them is (-9)/10 ,find the other
5. The sum of two rational numbers is (-3)/5, if one of them is (-9)/10 ,find the other.
6. A bag of wheat weighs 25 1/6 kg. What is the weight of 132 such bags?
7. Verify: x × (y + z) = (x × y) + (x × z) where x = (-3) ; y = 9/2 ; z = 7/6

Answer 1

Step-by-step explanation:

1) (-3)/7*(-9)/8=27/63

so multiplicative inverse is 63/27
