Simplify:2 1/3(4 1/4÷2)

kondor19780726 [428]

Answer:

$4\frac{23}{24}$

Step-by-step explanation:

We want to simplify:

$2\frac{1}{3}(4\frac{1}{4}\div 2)$

We convert to improper fraction to get:

$\frac{7}{3}(\frac{17}{4}\div 2)$

We now deal with the parenthesis by multiplying with the reciprocal of 2.

$\frac{7}{3}(\frac{17}{4}\times \frac{1}{2} )$

This gives:

$\frac{7}{3}(\frac{17}{8})$

We multiply to get:

$\frac{7}{3}(\frac{17}{8})$

This simplfies to:

$\frac{119}{24}$

We write as mixed number

$4\frac{23}{24}$

Radda [10]

Answer:

difference = 3, first term = 4

Step-by-step explanation:

given, a2 = 7

a9 = 28

wkt, a2 = a + d = 7

a9 = a + 8d = 28

- 7d = - 21

therefore d = 3

and wkt, d = a2 - a

a = 7 - 3 = 4
