The mass of two pieces of cheese is 1.4, one of them is 3 times heavier than the other, find the mass of a large piece.

Let’s solve this problem with the help of parts. Let one piece of cheese make up one piece and the other piece make up three pieces. The first action is to find how many parts are two pieces of cheese and this will be equal to 1.4 in mass. 1) 1 +3 = 4 (h) falls on a mass of 1.4; Let’s find what is the mass of one part. 2) 1.4: 4 = 0.35 – the mass of one part; 3) 0.35 * 1 = 0.35 – the mass of the first piece; 4) 0.35 * 3 = 1.05 – the mass of the second piece.
Answer: 0.35 and 1.05
