Question

1.44×(16+14)=44× + × 14= 2.12×(48+52-66)=12× + × 52- ×66= Треба вставити пропущені цифри Надо вставить пропущенные цифры

Answer 1

Ответ:

1.44×(16+14)=44× + 20× 14=44× + 280

2.12×(48+52-66)=12× + 4× 52- 6×66=12× + 208 - 396 = 12× - 188

Answer 2

Let's solve the equations step by step and find the missing digits.

1. 1.44 × (16 + 14) = 44 × _ + _ × 14

First, solve the expression inside the parentheses: 1.44 × (16 + 14) = 1.44 × 30 = 43.2

Now we have the equation: 43.2 = 44 × _ + _ × 14

Since the product of 44 and a number should be less than or equal to 43.2, and the product of a number and 14 should be greater than or equal to 43.2, we can deduce that the missing digits are:

44 × 1 + 3 × 14 = 43.2

Therefore, the missing digits are 1 and 3: 1.44 × (16 + 14) = 44 × 1 + 3 × 14

2. 2.12 × (48 + 52 - 66) = 12 × _ + _ × 52 - _ × 66

First, solve the expression inside the parentheses: 2.12 × (48 + 52 - 66) = 2.12 × 34 = 72.08

Now we have the equation: 72.08 = 12 × _ + _ × 52 - _ × 66

Since the product of 12 and a number should be less than or equal to 72.08, the product of a number and 52 should be less than or equal to 72.08, and the product of a number and 66 should be greater than or equal to 72.08, we can deduce that the missing digits are:

12 × 6 + 4 × 52 - 2 × 66 = 72.08

Therefore, the missing digits are 6, 4, and 2: 2.12 × (48 + 52 - 66) = 12 × 6 + 4 × 52 - 2 × 66

I filled in the missing digits based on the assumption that the equations are meant to be solved using whole numbers. However, if decimal or fraction values are allowed, the missing digits may be different.
