What is 7/3 + 4/7 ???????

Mathematics
1 answer:
rjkz [21]4 years ago
5 0

Answer:

2 19/21, 61/21

Step-by-step explanation:

First, lets make the denimonators, "3 and 7" common. 3 and 7 are prime numbers, so the common denonminator is "21".

For 7/3, multiply by "7/7" and for 4/7 multiply by "3/3".

49/21 + 12/21

Add.

61/21

61 is a prime number so this answer will be your final answer.

(unless you have to put it as a mixed number which would be 2 19/21)

Paige ran four miles a day last week. This week, she ran five miles a day. How did adding a mile most likely affect her workout?
Alik [6]

Answer:

A. It increased both her intensity and her workout time.

Step-by-step explanation:

A. It increased both her intensity and her workout time.

B. It decreased her intensity but increased her workout time.

C. It increased her intensity but decreased her workout time.

D. It decreased both her intensity and work out time

Last week = 4 miles per day

This week = 5 miles per day

Intensity refers to how hard one exercises.

Workout time refers to how long one exercises the body.

By adding a mile, she has increased how hard she exercises her body (intensity))

And also increased how long she exercises the body (workout time) because the time she spent on 5 miles per day is more than time spent on 4 miles per day

If I turned 9 on November 9th, 2015, exactly how old am I now? (Oct 16th, 2021)
inysia [295]

The answer to this is quite simple my friend.

So if you were 9, purely turning on November 9th of 2015 at a undisclosed time, you would've been born in November of 2006. Currently, now of October 16, 2021, you would be:

Add:

4 + 10 + 1 = 15

So you would be 15 years old.

Hope this helps, currently it's 10/17/2021 for me and 1:56 am (EST).

Have a nice morning, night, dusk etc.

Neil has 3 partially full cans of white paint. They contian 1/3 gallon, 1/5 gallon and 1/2 gallon of paint. About how much paint
pickupchik [31]

Answer:

1 1/30 gallon

Step-by-step explanation:

Can A = 1/3 gallon

Can B = 1/5 gallon

Can C = 1/2 gallon

Total paint Neil has = Can A + Can B + Can C

= 1/3 + 1/5 + 1/2

The lowest common multiple of 3, 5 and 2 is 30

= (10+6+15) / 30

= 31/30

= 1 1/30 gallon of paint

Neil has a total of 1 1/30 gallon of paint
