8 pounds of ground beef costs 23.31 what is the cost per pound? how would you round answer to the nearest cent. Can somebody help me with that.
Answered by Ms. Sue
23.31 / 8 = 2.91375

Since 3 is less than 5, the cost per pound is $2.91

I need somebody to help me with this question 4 over 5 divide 8 over 3 subtract 1 over 5, is it 1 over 15 or 8 over 35, 1 over 10 or 12 over 37, I'm having a hard time understanding it.
Answered by Reiny
Why don't you just type it using the language of arithmetic?

did you mean:
(4/5) รท (8/3) -1/5 ?
then
= (4/5)(3/8) - 1/5
= 3/10 - 2/10
= 1/10

remember , when dividing one fraction by another
write down the first fraction, TIMES the reciprocal of the second. That is what I did above.
Of course follow the order of operation, multiplication and division comes before addition or subtraction.

I'm having problem understanding convert the fraction to a decimal and round to the tenths place 15 over 17,can somebody help me with this question.
Answered by Ms. Sue
Divide the numerator by the denominator.

15/17 = 0.882

The tenths place is the number just to the right of the decimal. If the next number is 5 or more, round the number in the tenths place up to the next number,

I'm having problem adding 4 2/5+4 2/6 I even don't understanding the insert the appropriate symbol<,>, or = 0.4 blank 0.8, is it <, >, or = I need all the help I can get right now
Answered by Cambridge
*facepalm* Could you maybe post as a separate question not as a continuous chain?

Anyway 4 2/5 = 22/5
4 2/6 = 2
Answered by Cambridge
Whoops sorry
4 2/6 = 26/6
22/5 = 6*22 / 30
26/6 = 26*5 / 30

thus we have
(6*22 + 26*5 )/30

so we have 262/30
= 8 22/30 = 8 11/15
