Question

1 3/5 ×0,5+0.16× 1 1/4

Answer 1

1 3/5 ×0,5+0.16× 1 1/4
Переводим десятичные дроби в обыкновенные:
0,5=5/10=1/2
0,16=16/100=4/25
Получаем: 1 3/5*1/2+4/25*1 1/4
Обыкновенную дробь переводим в неправильную и считаем:
8/5*1/2+4/25*5/4=4/5+1/5=5/5=1

Answer 2

To solve this expression, we need to follow the order of operations, which is typically remembered by the acronym PEMDAS (parentheses, exponents, multiplication and division, and addition and subtraction).

1 3/5 × 0.5 + 0.16 × 1 1/4

First, we can simplify the mixed numbers to improper fractions:

1 3/5 = (1 × 5 + 3)/5 = 8/5 1 1/4 = (1 × 4 + 1)/4 = 5/4

Now, we can substitute these values into the expression:

8/5 × 0.5 + 0.16 × 5/4

Next, we can perform the multiplication:

(8/5) × 0.5 = 4/5 0.16 × (5/4) = 0.2

Now, we can add these two values:

4/5 + 0.2 = 1

Therefore, the expression 1 3/5 × 0.5 + 0.16 × 1 1/4 simplifies to 1.
