Which is the best estimate of the product of the fractions? StartFraction 4 Over 7 EndFraction times StartFraction 8 Over 9 EndF
Lapatulllka [165]

Answer:

Product = \dfrac{64}{135}

Step-by-step explanation:

The expression is as follows :

\dfrac{4}{7}\times \dfrac{8}{9}\times \dfrac{14}{15}

We need to find the product of the above expression

As 7 × 2 = 14

So, it will become :

4\times \dfrac{8}{9}\times \dfrac{2}{15}\\\\=\dfrac{4\times 8\times 2}{9\times 15}\\\\=\dfrac{64}{135}

So, the product of the given fractions is \dfrac{64}{135}.
