Write an expression to match the statement.
To find the volume of a box that has a 40 by 23 base and 50 layers, I multiply the dimensions of the base first and then multiply by the number of layers.
(40 x 23) x 50
this box has 14 balls in one layer and has 3 layers. how many balls can the box hold?
42 balls
divide 100 / 17 using a ratio table
5 R15
Write an expression for the statement
"To find 14 x 15, I double and halve"
14 x 15 = 7 x 30
write and solve the equation represented by the statement
to find 15 times 23, I multiply 10 times 23 and add it to 5 times 23.
(10 x 23) + (5 x 23) = 345
