Does anyone know how to solve this

first and third quadrants

the answer B

Step-by-step explanation:

on the first quadrant x and y are both positive

in the second one x is negative and y positive so -x/y=-1

on the third quadrant x and y are both negative

so -x/-y=1

on the fourth quadrant x is positive and y negative so

x/-y=-1

here, in all cases x and y are taken the same length that's why we take always 1 or -1

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
