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:
(b)
Step-by-step explanation:
The hundredths place is immediately to the left of the thousandths place. In our base-10 number system, moving a digit to the left one place increases its value by a factor of 10.
The value of 7 in the hundredths place is 10 times the value of 7 in the thousandths place.
