Answer:
The answer for this question would be 85 and 17/20 or /20
Step-by-step explanation:
You must first find the LCD of these terms (everything that is separated by the addition signs).
The LCD is 20 because:
2 x 10 = 20
5 x 4 = 20
4 x 5=20
and there is no number lower than 20 that all of these numbers share in their multiplication table.
Now you must multiply every term by the number you used to make its denominator 20. Since 2 x 10 = 20, the new term would be:
60 10/20
Since 5 x 4 = 20, the new term would be:
4 12/20
Since 4 x 5 = 20, the new term would be:
20 15/20
Now we put all the whole numbers and numerators together to get:
60 + 4 + 20 = 84 - whole numbers
10 + 12 + 15 = 37 - numerators
84 37/20 = 85 17/20 or 1717/20
Answer:
10:7
Step-by-step explanation:
40:28 are both divisible by 4. 40/4 is 10. 28/4 is 7. So the ratio would be 10:7 since neither is divisible by both the same number, this is the final ratio.
The total means add so,
42 + 75 + 189 + 301 + 728 = 1,335
