During a wagon race there were 140 horses in total, and 20 wagons. Each wagon had the same number of horses. Choose the equation that represents the total number of horses. \(?\)

\(20 \, \times \, x \, = \, 140\)

\(20 \, \div \, x \, = \, 140\)

Last week Natalie looked at the apple tree and there were 16 apples. This week there are 35 apples. Which equation solves to tell us how many new apples there are on the tree? \(?\)

\(35 \, \times \, 16 \, = \, x\)

\(x \, \times \, 35 \, = \, 16\)
