What is the question if it 98-49 than it would be 49
2/3 ÷ 4 = 2/3 * 1/4 = 2/12 = 1/6
This question basically asks for the LCM of 3 and 5, which is 3 x 5 =15
This is the answer: 15
Check : The first rectangle had 1/3 shaded; ( one in every three parts)
So for 15 parts altogether, 5 would be shaded ( 1/3 = 5/15)
The second rectangle had 2/5 shaded ( two for every five parts)
So for 15 parts altogether, 6 would be shaded (2/5 = 6/15)
46
When it says f(4) that means x=4
So you then just fill in all the x’s with 4’s and solve as normal
