1. Вставь пропущенные числа. [ ] * 2 = 300 4 * [ ] = 600 5 * [ ] = 700 [ ] * 3 = 390 : 4 = 120 : 6 = 120 : 3 = 310 : 2 = 420

\( 150 \cdot 2 = 300 \)

\( 4 \cdot 150 = 600 \)

\( 5 \cdot 140 = 700 \)

\( 130 \cdot 3 = 390 \)

\( 480 : 4 = 120 \)

\( 720 : 6 = 120 \)

\( 930 : 3 = 310 \)

\( 840 : 2 = 420 \)
