Answer:

d.)

Step-by-step explanation:

Start with the brackets first.

(−1/4−1/2) = −1−2 ÷4 = −3/4

Hence we get:

−3/4÷(−4/7)

which is equal to

-3/4×(−7/4) −3/4×(−7/4) = 21/16

which then u convert 21/16 into a mixed fraction to get 1 5/16

frutty [35]

Answer:

Step-by-step explanation:

Change the 2/3 to 4/6

Now the ratio becomes 3:4:6

So the number of each is

3x + 4x + 6x = 520

13x = 520

x = 40

Red = 3*40 = 120

Yellow = 4*40 = 160

Blue = 6 * 40 = 240

Total = 520
