What is is 10 7/78 divided by 4 7/85 ?

Question

Maths question I do not understand!

Answer 1

First convert each to a true fraction (not a mixed number). For instance, if a number was 10 1/4, the fraction is 41/4 (10*4+1)/(4)

Then you multiply the reciprocal of the second fraction by the first--if you had "37/16 divided by 19/5", this is the same as "37/16 times 5/19" or (37 x 5)/(16 x 19).

Once you have the (large, in your example) numerator and denominator, then you have to find the greatest common denominator and reduce the fraction. Lucky for you there is no GCD other than 1 in yours, so you don't have to reduce the fraction you'll ultimately arrive at.

Answer 2

78 Divided By 7

Answer 3

since it a mixed fraction you get
change the numerator (10 7/78) to [10*78 +7] /78 you get 787/78 and change the denominator (4 7/85) it to [4*85+7] /85 you get 347/85
So the above question can now be written as [ 787/78]/ [347/85]
when you divide two fractions you multiply the recripocal of the denominator with the numerator and then you get [787*85]/ [347*78]
put that into the calculator and you should get 2.471551023.

Answer 4

10 7/78 divided by 4 7/85

787/78 divided by 347/85

When you divide by a fraction, it is the same as multiplying by the Reciprocal.

So, this is the same as saying
787/78 * 85/347

66895/27066

2 12763/27066

I have to go so I don't have time to see if I can simplify this fraction further. Good Luck.

Answer 5

10 7/78 divided by 4 7/85

= {[(10*78)+7]/78 } / {[(4*85)+7]/85}

= { 787/78} / {347/ 85}

= {787*85} / {78*347}
= 66895/ 27066
= 2.4716

Answer 6

10 7/78 divided by 4 7/85

= {[(10*78)+7]/78 } / {[(4*85)+7]/85}

= { 787/78} / {347/ 85}

= {787*85} / {78*347}
= 66895/ 27066
= 2.4716

Answer 7

first make compound fractions
10 7/78 = 787/78
4 7/85 = 347/85
invert and multiply
787 * 85 = 66895
78 * 347 = 27066
66895/27066 = 2.47155
