Question

Erlinda finished her math test in 5 1/2 minutes. Lacsalie finished in 8 1/3 minutes how many minutes ahead was Erlinda?
Number of sentence:________
Answer:______________​

Answer 1

➤ Answer :-

Timing took by Erlinda :- $\sf 5 \frac{1}{2}$

Timing took by Lacsalie :- $\sf 8 \frac{1}{3}$

How many minutes ahead was Erlinda :-

$\longmapsto \sf \: 8 \frac{1}{3} - 5 \frac{1}{2}$

$\longmapsto \sf \: \frac{25}{3} - \frac{11}{2}$

LCM of 3 and 2 is 6.

$\longmapsto \sf \: \frac{25 \times 2}{3 \times 2} - \frac{11 \times 3}{2 \times 3}$

$\longmapsto \sf \: \frac{50}{6} - \frac{33}{6}$

$\longmapsto \sf \: \frac{50 - 33}{6}$

$\longmapsto \sf \: \frac{17}{6} = 2 \frac{5}{6}$

$\Huge\therefore$Erlina was $\sf 2 \frac{5}{6}$ ahead than Lacsalie.

Answer 2

Answer:

Hi dear, here is your solution. Also, it should not be how many minutes Erlinda is ahead, it shall be how many minutes Lacsalie is ahead. okay?

Step-by-step explanation:

Erlinda= 5 1/2 min.

lacsalie = 8 1/3 min.

Time required by Erlinda- time required by lacsalie.

8 1/3 - 5 1/2

now substract them and you will get the answer. I hope it helped.
