alexdok [17]

Answer: x = 10.3 ÷ 4

Step-by-step explanation: if we were to work this out forgetting about the equation it can be worked out by dividing the 10.3 by 4 to find the length of the pieces so, now to express it as an equation, we have to add x into our sum 4 × ? = 10.3 : 4x = 10.3. The answer for x would be x = 2.58.

Explain how to evaluate a + b ÷ c, when a = 1 2/5, b = 2 2/5, and c = 3/4. You do not have to compute the values.

raketka [301]

Answer:

The correct answer is: $4\frac{3}{5}$

Step-by-step explanation:

According to the rule of BODMAS, division is done before addition.

So, in a + b ÷ c, we will first calculate, b ÷ c

Given b = $2\frac{2}{5}$ = $\frac{12}{5}$ , c = $\frac{3}{4}$ .

So, $\frac{b}{c}$ = $\frac{12}{5}$ ÷ $\frac{3}{4}$

So, $\frac{b}{c} = \frac{12}{5} \times\frac{4}{3}$ , as the numerator and denominator gets reversed as division is changed to multiplication.

So, $\frac{b}{c} = \frac{16}{5}$ .

Next the value of a to $\frac{b}{c}$ , where, $a = 1\frac{2}{5} = \frac{7}{5}$ , we get,

$\frac{7}{5} +\frac{16}{5} = \frac{23}{5} = 4\frac{3}{5}$ .
