Question

A bag is filled with small and large marbles. The ratio of small to large marbles is 1:3. On your own sheet of paper, draw a tape diagram to represent this situation. There are eight more large marbles than small marbles. On your diagram, how many marbles does each bar represent? [Type your answer as a number.]

Answer 1

Tape diagrams are simple. Look at the picture I put in the comments

Answer 2

Ratio of Small to large marbles in the bag=1:3

It means ,number of small marbles in the bag will be multiple of 1 and number of Larger marbles in the bag will be multiple of 3.

So, number of small marbles be x and number of large marbles be 3x.

It is also given that, there are eight more large marbles than small marbles in the bag.

Expressing this statement in terms of equation

→3x=x+8

3x-x=8

2x=8

Dividing both sides by, 2 we get

x=4

Number of Small marbles =4 Marbles

Number of Large Marbles =4×3=12 Marbles
