Answer 1

Ответ:

7×15=7×(10+5)=7×10+7×5=70+35=105

6×17=6×(10+7)=6×10+6×7=60+42=102

3×31=3×(30+1)=3×30+3×1=90+3=93

65÷5=(60+5)÷5=60÷5+5÷5=12+1=13

56÷4=(40+16)÷4=40÷4+16÷4=10+4=14

Answer 2

Давайте решим каждое уравнение поочередно:

1. $4 \times 23 = 4 \times (20 + 3) = 4 \times 20 + 4 \times 3 = 80 + 12 = 92$

2. $7 \times 15 = \_ \times (\_ + \_) = \_ \times \_ + \_ \times \_ = \_ + \_ = 105$

3. $6 \times 17 = \_ \times (\_ + \_) = \_ \times \_ + \_ \times \_ = \_ + \_ = 102$

4. $3 \times 31 = \_ \times (\_ + \_) = \_ \times \_ + \_ \times \_ = \_ + \_ = 93$

5. $65 \div 5 = (\_ + \_) \div \_ = \_ \div \_ + \_ \div \_ = \_ + \_ = 13$

6. $56 \div 4 = (\_ + \_) \div \_ = \_ \div \_ + \_ \div \_ = \_ + \_ = 14$
