Math helps with science because you'll need to know the math in order to convert units in science.
Answer:
4/3
Step-by-step explanation:
4/10 / 3/10
4/10 * 10/3
The 10s cancel out and you are left with
4/3
You can solve this by using "similar triangles".
In triangle ABC, we are looking for side AC which is x. Side AC is similar to side DF in triangle EDF.
You can solve for side x by picking two sides in triangle ABC and their corresponding sides in triangle EDF. This is what I mean:

Substitute for the values of AC, BC, DF and EF:


To solve for y, do the same thing. Pick two sides on triangle ABC and their corresponding sides in triangle DEF.

Substitute for the values and solve:


We have the value x to be 5.5 units and y to be 6 units.
6/16 & 3/8. Hope it helped.
