Let's start by comparing the four given masses in order:
1. 800 grams
2. 2 kilograms
3. 1 tonne
### Convert all masses to the same unit (grams):
- 2 kilograms: Since 1 kilogram is 1000 grams, 2 kilograms is [tex]\(2 \times 1000 = 2000\)[/tex] grams.
- 1 tonne: 1 tonne is equal to 1000 kilograms, and since 1 kilogram is 1000 grams, 1 tonne is [tex]\(1000 \times 1000 = 1,000,000\)[/tex] grams.
- 800 grams: This is already in grams.
So, we have:
1. 800 grams
2. 2000 grams (2 kilograms)
3. 1,000,000 grams (1 tonne)
### Order them from lightest to heaviest:
1. 800 grams
2. 2000 grams (or 2 kilograms)
3. 1,000,000 grams (or 1 tonne)
Thus, we write the masses in order from lightest to heaviest:
1. 800 grams
2. 2 kilograms
3. 1 tonne
Next, we need to determine two 2-digit numbers that multiply to make 176.
### Find the factors of 176 that are 2-digit numbers:
We look for 2-digit numbers [tex]\(a\)[/tex] and [tex]\(b\)[/tex] such that [tex]\(a \times b = 176\)[/tex].
The possible pairs that satisfy this condition are:
- 11 and 16
- 16 and 11
Thus, the two 2-digit numbers that multiply to 176 are 11 and 16.
### Final Answers:
1. Order the masses from lightest to heaviest:
- 800 grams
- 2 kilograms
- 1 tonne
2. The two 2-digit numbers that multiply to 176:
- 11
- 16
