Question

the rational number is -1/2 when you multiply it by 2/5 and 2/3 is added to the product you get 7/15​

Answer 1

Answer:

yes the question is absolutely correct as LHS =RHS

Step-by-step explanation:

$(- 1 \div 2)\times (2 \div 5) + (2 \div 3) = (7 \div 15) \\ (- 1 \div 5) + (2 \div 3)= (7 \div 15) \\ (- 3 + 10) \div 15 = (7 \div 15 )\\ (7 \div 15) =( 7 \div 15)$
