Maths Test 4.3ABCD

Answer explanation

The expression \(\frac{4}{10} + \frac{3}{10} + \frac{3}{10}\) sums to \(\frac{10}{10}\), which exceeds \(\frac{7}{10}\). The other options correctly sum to \(\frac{7}{10}\).

Answer explanation

The correct choice, \(\frac{2}{4} + \frac{2}{4} + \frac{3}{4} = \frac{5}{4} + \frac{2}{4}\), shows two ways to represent \(\frac{7}{4}\) by combining fractions that equal the same total.

Answer explanation

To find an equivalent expression for \(\frac{4}{3}\), we can rewrite it as \(\frac{1}{3} + \frac{1}{3} + \frac{1}{3} + \frac{1}{3}\), which sums to \(\frac{4}{3}\). Thus, the correct choice is \(\frac{1}{3} + \frac{1}{3} + \frac{1}{3} + \frac{1}{3}\).

Which number sentence represents two different ways of the sum 7/6 ?

Answer explanation

The correct choice, \(\frac{3}{6} + \frac{4}{6} = \frac{2}{6} + \frac{5}{6}\), shows two ways to represent \(\frac{7}{6}\) using shaded fractions, confirming both sides equal \(\frac{7}{6}\).

Answer explanation

Jeffery has 3 liters of fresh water and 1 liter of salt water, plus the fractional parts. The correct equation combines these amounts: 3 + 1 + \frac{2}{9} + \frac{3}{9} = 4\frac{5}{9}, which gives the total liters.
