4/5 + 3/4 =
marshall27 [118]

The topics you should learn are equating denominators and fractions. This is summing up simple fractions.

So we have to make denominators' numbers the same in order to sum up them all (we can sum fractions if the denominators are the same) , and we did it by cross product (that thing on the picture)

Equating by lcm (least common multiple) is the easiest way, because you might see bigger numbers on other questions, and cross product will bring much bigger numbers, so this technic might confuse you.

By the way lcm of 4 and 5 is already 20

Hope it helps!

Ilia_Sergeevich [38]

Answer:

The weight of 12 tennis balls  =  691. 2 grams

Step-by-step explanation:

The weight of each  tennis ball =  57.6 grams

So, the weight of 12 balls    =    12 x ( weight of 1 ball)

                                              = 12 x 57.6 grams

                                              = 691.2 grams

⇒12 balls weigh 691.2 grams

Hence, the weight of 12 tennis balls  =  691. 2 grams
