Question : 8 of 100

Marks: +1, -0

5\frac{17}{37} \times 4\frac{51}{52} \times 11\frac{1}{7} + 2\frac{3}{4}

= ?

303.75
305.75
303 $\frac{1}{4}$
$305\frac{1}{4}$
None of these

Solution:

Concept:

Convert mixed fractions to improper fractions, simplify the product, then add the remaining mixed fraction.

Explanation:

5\frac{17}{37}=\frac{202}{37}

4\frac{51}{52}=\frac{259}{52}

11\frac{1}{7}=\frac{78}{7}

2\frac{3}{4}=\frac{11}{4}

Now multiply:

\frac{202}{37}\times\frac{259}{52}\times\frac{78}{7}

Since

259=37\times7

, cancel

37

and

7

:

=\frac{202\times78}{52}

=\frac{202\times3}{2}

=101\times3=303

Add

2\frac{3}{4}

:

303+\frac{11}{4}=303+2.75=305.75

So the correct value is

305.75

, which matches option B.

Answer:

305.75
