Answer:
9 pencils
Step-by-step explanation:
We know that the ratio is 5:3 and its pens to pencils. So, every 5 pens have 3 pencils. Now Jose has 15 pens, so his pen supply triples. therefore his pencil supply must also triple. So 3x3=9.
Let the no. of pencils be x,
= 5/3 = 15/x
Do cross multiplication
= 5x = 15 × 3
= x = 45/5
= x = 9
No of pencils = 9
