Samuel's answer to Vera's Primary 5 Maths Fractions Singapore question.
Sorry, what is the total mass of the two balls?Is it answer is 51/7.
Hi, no. The steel ball is 51/7. As it is 3times heavier than iron. So if you want total, u need steel plus iron
Sorry i didn’t read the question properly. So 51/7 + 17/7 =68/7
Ok, thank you so much!
No problem
