Question

Joyce says that if 5x = 4y, then x : y = 5 : 4. Explain if Joyce is right or wrong.

Answer 1

Answer:

Joyce is wrong

Step-by-step explanation:

Joyce is wrong

given 5x=4y

x/y = 4/5

this implies x:y = 4:5

Answer 2

Joyce is wrong

if, 5x=4y

=5×4=4×5

=20=20

=x:y::5:4

=4:5::5:4

= 5×5=4×4

=25>20

=Therefore, Joyce is wrong
