Marcus can type 40 words in half a minute. rhys can type 100 words in one and a half minutes. which student can type at a greater rate of words per minute

Marcus can type faster

explained:

40in 1/2

40+40= 80 in 1min.

100in 1 1/2

1 1/2 =3/2

100/3/2 = 66.7

how to get rid of a fraction you have to multiply so to get rid of 3/2 have to multiply by 2/3 and everything you do to the body have to do to the top so hundred times 2/3 is going to give you a six six point and then six keep going or we're going to round it up to seven so 66.7 which mean Marcus types faster because he types 80 per minute
