Their combined weight would be 7 2/14. here are the steps of how I got my answer.
1. I made the answers into improper fractions. 3 1/2= 7/2 and 4 1/7= 29/7.
2. then I found the least common multiple (LCM) of 2 and 7 which is 14.
3. next in order to make both denominators become 14 I cant just make 7/2 into 7/14 and 29/7 into 29/14. so I multiplied 29/7 by 2 which got me 58/14 and 7/2 by 7 which got me 42/14.
4. then I did 42/14+ 58/14= 100/14.
5. Then the last step was to make the improper fraction 100/14 into a proper fraction. Now how do you do that? BY DIVIDING! I divided 100 by 14 and I got my answer of 7 2/14.
Hope this helped! :)
Answer:
20 students in science class, 25 in math
Step-by-step explanation:
so let 1 classroom= x
so the other classroom= x+5
if there is a total of 45 students
x+x+5=45
2x=45-5
2x=40
x=20
Answer:
Step-by-step explanation:
21/8 * 4/1 = 21/2 = 10.5 cups
Answer: (g+f)——>squareroot 3 - 3
(g-f)——>squareroot 15
(f/g)——> 0
(g•f)——>-3 squareroot 3
Step-by-step explanation:
For the G and F functions, plug the number in the parentheses from the boxes.
Hope I explained it good enough!
