Question

A jar has marbles in it. Three tenths of the marbles are red. Five tenths of the marbles are blue.

Two tenths of the marbles are green. Which of these fractions is equivalent to four eighths?

Answer 1

The red marbles are 3/10 of the total.

The blue ones are 5/10 of the total.

The green ones are 2/10 of the total.

Of these, 5/10=1/2=(1×4)/(2×4)=4/8

Therefore, five tenths is equivalent to four eighths.
