50× 3/8 how to reduce answer to lowest te
hoa [83]

The lowest term is \frac{75}{4}.

Solution:

Given expression is 50\times\frac{3}{8}

<u>To reduce this term to the lowest term:</u>

$50\times\frac{3}{8}=\frac{50}{1}\times\frac{3}{8}

Multiply the numerator and denominator.

$50\times\frac{3}{8}=\frac{150}{8}

Now, divide the numerator and denominator by the greatest common factor.

Here 150 and 8 both have common factor 2.

So, divide numerator and denominator by 2.

           $=\frac{150\div2}{8\div2}

           $=\frac{75}{4}

$50\times\frac{3}{8}=\frac{75}{4}

Hence the lowest term is \frac{75}{4}.

Calculate the perimeter for the parallelogram if a= 7.6 , b= 5.9 and c= 14.6
kolezko [41]

Although the problem gives the value of b, it's really not needed.

Opposite sides of a parallelogram are congruent, so we just need to calculate: 2a + 2c = P

Plug the given values in:

2 * 7.6 + 2 * 14.6 = 44.4 units, or choice (C).
