P4P5 Reverse Model Drawing (Before and After Fractional Change)

This exercise below aims to help students better understand before and after models by having them look at the already completed models and have them fill in the blanks to the original problem sum description.

While these are not exam questions, they help students to structure their thinking process for the formation of the equations(number sentences) needed to solve such questions.




Given the before and after model above, 
fill in the blanks.

Luke has ___ times as many toy cars as Marvin at first.
After Luke gave away __/__ of his toy cars.
He now has equal number of toy cars as Marvin.
Luke have 13 toy cars at the end.
They have ___ toy cars altogether at first.

P5P6 Math: Before and After (One Party Change) Fractional Comparison

Such questions are very similar to before and after "ratio" comparison where only one of the values changed, but the ratios are expressed using fractions. 

Such questions are common in Paper 2 of P5 and P6 exams.
Calculator usage is allowed.

Similar Ratio (One Party Change) questions can be found here.

Ben and Lenny each have some baseball cards.
At first, Ben has 2/5 as many cards as Lenny.
After Ben bought 36 more cards,
Ben has 2/3 as many cards as Lenny.

How many cards did both boys have altogether at first?
