Answer:

a = 1/42; b = 1/7; c = 1/3; d = 1/2

Step-by-step explanation:

a = bcd

a + b = cd

a + b + c = d

a + b + c + d = 1

d + d = 1

2d = 1

d = 1/2

2a = bc

2a + 2b = c

2a + 2b + 2c = 1

bc + 2b = c

bc + 2b - c = 0

bc + 2b + 2c = 1

-3c = -1

c = 1/3

a + b = cd

a + b = 1/6

a = bcd

a = b(1/3)(1/2)

a = 1/6 b

1/6 b + b = 1/6

7/6 b = 1/6

b = 6/42

b = 1/7

a = 1/6 b

a = 1/6 * 1/7

a = 1/42

There will be 180 mL of water left.

To convert liters to milliliters, multiply by 1000:
0.4(1000) = 400

Each student will use two 5-mL spoons of water; 2(5) = 10 mL each. 10(22) = 220 total mL

400-220 = 180 mL left
