Question

7.Вычисли 648*475/(1458-1306) 816*502/(85117-84913) (912/114+6440/23)/16 288*703/(405060-404916)

Answer 1

$648$ × $475$ ÷ $(1458 - 1306) = 648$ × $475$ ÷ $152 = 307800$ ÷ $152 = 2025$

$816$ × $502$ ÷ $(85117 - 84913) = 816$ × $502$ ÷ $204 = 409632$ ÷ $204 = 2008$

$(912$ ÷ $114 + 6440$ ÷ $23)$ ÷ $16 = (8 + 6440$ ÷ $23)$ ÷ $16 = (8 + 280)$ ÷ $16 = 288$ ÷ $16 = 18$

$288$ × $703$ ÷ $(405060 - 404916) = 288$ × $703$ ÷ $144 = 202464$ ÷ $144 = 1406$

Ответы: $2025$; $2008$; $18$; $1406$.

Answer 2

Давайте поочередно рассмотрим каждое выражение:

1. $648 \cdot \frac{475}{1458-1306} = 648 \cdot \frac{475}{152} = 648 \cdot 3.125 = 2025$.

2. $816 \cdot \frac{502}{85117-84913} = 816 \cdot \frac{502}{204} = 816 \cdot 2.4608 = 2009.1648$.

3. $\frac{912}{114} + \frac{6440}{23} = 8 + 280 = 288$.

4. $288 \cdot \frac{703}{405060-404916} = 288 \cdot \frac{703}{144} = 288 \cdot 4.8819 = 1405.3952$.

Итак, результаты вычислений:

1. $2025$.
2. $2009.1648$.
3. $288$.
4. $1405.3952$.
