Okay so.
2/5=24/60 (multiply 2/5 by 12)
2/3=40/60 (multiply 2/3 by 20)
1/4=15/60 (multiply 1/4 by 15)
Then,
Add 24/60 with 40/60 which is 64/60 after you get that you subtract by 15/60 and you get 49/60.
Hope this helps!^^
I have included a picture. In the picture you will find the work and final answer.
10 to the sixth power is 1,000,000. Any number to the tenth power is the number 1 in front of the number of zeros that is equal to the exponent.
