Let 4units represent 800g, since the ratio of the masses is 7:5:4, with 800g being the lightest.
1 unit = 800/4 = 200g
hence, the mass of the heaviest cake will be 7 units, which is 7 x 200g = 1400g
Answer:

a = 3.745 (rounded) or 3.7464 (exact)
b = 7
Step-by-step explanation:
Assuming you meant "a person takes 8.4 x 10^6 breaths
