In a storeroom, there are 30 blue balls, 48 green balls, some red balls Ind some white balls. There are 3 times as many green balls as red balls and 5 times as many blue balls as white balls. 
(a) How many balls are there altogether?

(b) How many balls are left in the room if 7/10 of the balls are taken away?

Red balls = 48 / 3   = 16

 

White balls = 30 / 5 =  6

 

Total balls =  30 + 48 + 16 + 6 =   100

 

If 7/10  are taken away  3/10  must  remain......can you solve it ???

100 * (3/10) = 30
 

There will be 30 balls remaining
