ram weighs 45kg and mary weighs m kg.
write an expression for their combined weight.
45kg + m kg
To write an expression for the combined weight of Ram and Mary, we need to add their individual weights together.
Ram weighs 45 kg, so we can represent this by the expression: 45
Mary's weight is given as "m" kg, so we can represent this by the expression: m
To find their combined weight, we add these two expressions together: 45 + m
Therefore, the expression for their combined weight is: 45 + m
