$.07. You do not write $.7 because that would mean 70 cents and should be written with a 0 at the end anyways. You do not write any dollar amount with a cents sign at the end, because the dollar sign replaces it. You write $.07 because 7 cents means 7/100 (7 one hundredths) so the seven must be written in the hundredths spot. Remember, the hundredth spot is the second number after a decimal.
0.377 + 5.51 = 5.887
Sorry I can only solve the first one. Could you give me a hint on how to do the second one ?
<span>How
the value of 8 in 880 related
=> 880 = 8 hundreds 8 tens
=> This given number is a whole numbers, thus the value of 8 in the hundreds
place is ten times larger than the 8 In the tens place. How?
Try multiplying 8 tens by 10
=> 8 tens = 80
=> 80 x 10
=> 800
When 80 is multiplied by ten the answer is 800 and when 800 is divided by 10
the answer is 80.
That concludes that there’s 10 times difference between the two 8s in the given
number.</span><span>

Multiply the second fraction by two; which gets you 5/10 + 2/10 = 7/10
