Answer 4

can you help me

Answer 5

?

Answer 6

sure, lets write the given info in numbers :-

8 and one-third times 2 and four-fifths
\(\large 8 \frac{1}{3} \times 2 \frac{4}{5}\)

Answer 7

lets estimate first,
you're multiplying 8 and somthing, with 2 and something, so, the answer must be greater than 16 only.

Answer 8

can we estimate any bettter ?

Answer 9

yes?

Answer 10

good, wat is that ?

Answer 11

idk?

Answer 12

on top of 16, see that you're taking 4/5 of 8

Answer 13

that should give you 6+
so total the answer must be atleast 16+6 = 22

Answer 14

next, compute the actual product and see how bad/good is our estimation

Answer 15

is dont know how to do that

Answer 16

i

Answer 17

good?

Answer 18

\(\large 8 \frac{1}{3} \times 2 \frac{4}{5} \)

Answer 19

can you show it all together now plz

Answer 20

first convert mixed fraction to simple fraction...

Answer 21

\(\large 8 \frac{1}{3} \times 2 \frac{4}{5} \)

\(\large \frac{25}{3} \times \frac{14}{5} \)

Answer 22

now you can multiply easily i hope :)
btw, did u get how 8 1/3 became 25/3 ?

Answer 23

can you show it all together plz

Answer 24

okay see if the below working helps

\(\large \large \frac{25}{3} \times \frac{14}{5}\)

\(\large \frac{\cancel{25}^{5}}{3} \times \frac{14}{\cancel{5}}\)

Answer 25

\(\large \large \frac{25}{3} \times \frac{14}{5}\)

\(\large \frac{{5}}{3} \times 14\)

Answer 26

\(\large \frac{70}{3}\)

\(23.333\)

Answer 27
