4 by 5 of the remaining honey over sandwiches. How much honey remains?
Express it in L.​

Answer 1

Answer:

$0.087$L or $87\times10^{-3}$L

Step-by-step explanation:

$1$L$=1000$mL

Hence, Mrs. Tewari has $1000+160=1160$mL

Now, she gave $\frac{5}{8}$ of $1160$mL to her friend, that is $1160\times\frac{5}{8}=145\times5=725$mL

Remaining$=1160-725=435$mL

Of the remaining, she spread $\frac{4}{5}$ of it over sandwiches, that is $435\times\frac{4}{5}=87\times4=348$mL

Remaining after spreading it on sandwitches$=435-348=87$mL

In L, $0.087$L or $87\times10^{-3}$L
