5 1/6 as 30 goes into 6 times tables, and there would be a remainder of 1
Answer: 4/3 hours or 1 1/3 hours
Step-by-step explanation:
From the question, we are told that two mechanics, Martin and Gordon, are working on your car. Martin can complete the work in 4 hours, while Gordon can complete the work in 2 hours.
Since Martin can complete the work in 4 hours, that means in 1 hour, he will do 1/4 of the work.
Since Gordon can complete the work in 2 hours, that means in 1 hour, he'll do 1/2 of the job.
When they both work together, we will add their fraction of work done in one hour together. This will be:
= 1/4 + 1/2
= 3/4
This means that both of them will do 3/4 of the job in one hour. Then to get the time taken to get the whole job done, we divide 1 by 3/4. This will be:
= 1 ÷ 3/4
= 1 × 4/3
= 4/3 hours
= 1 hour 20 minutes.
In one
Answer:
40
Step-by-step explanation:
80% of the test = 32 questions
100% of the test = x questions
Cross multiply
80*x = 100 * 32 Combine the right
80x = 3200 Divide by 80
x = 3200/80
x = 40
There are 40 questions on the test.
