What is an equation?

An equation is an expression that shows the relationship between two or more variables and numbers.

1 yard = 36 inches

1 inch = 2.54 cm = 0.0254 m

Hence:

1800 yard = 1800 yard * 36 in per yard = 64800 in

64800 in = 64800 in * 0.0254 m per in = 1645.92 m

Since there are 245 metres of wool in each ball of wool. hence:

Number of wool balls = 1645.92 m / 245 m = 6.72

Linda needs to buy about 7 balls of wool to knit a baby’s blanket.
