Calculating digit values

I'm looking at a problem where Sum 4 indicates that a is likely 1, and there's no carry to the units. For the tenths, it seems that 9 plus c plus a carry from hundredths equals zero, suggesting c might be 1. I need to work this out step by step from the right:

Starting with thousandths, 1 plus d equals either 6 or 16, leading to d being 5. Moving on to hundredths, b plus 5 gives 3 mod 10, which means b is 8. Then for tenths, I find c equals 0. Finally, a plus 2 leads to a being 1. So, I think I have 1,908 plus 2,055 equals 3.963? Wait, I'm mapping the digits now.Inspecting digit alignment

I see that the result 16,327 has two integer digits and three decimals, which doesn't quite align. The expression *5,*1 suggests that there’s one star before 5 for two integer digits, and then one after the comma for two decimal digits, but I have three. Maybe the stars represent digits?
Zooming into the image, it appears the text might actually read as *5,**1. I should inspect the visual closely, especially the pixels or coordinates in the image.Solving numerical problems

I'm working through some calculations. For the first units, I'm finding results using borrowing methods. It looks like when I take 5 and subtract C, then add 10, I determine C is 9, yielding a first result. Next, with the tens, A comes out to 2, leading to the subtraction 25.41 - 9.083 equaling 16.327.

Then, with another set of calculations, I'm solving for digits in a larger subtraction problem involving decimals. I'll keep refining this to clarify solutions!Conducting digit subtraction

I'm diving into a digit subtraction process. Starting from the rightmost thousandths, I see I need to borrow from the hundredths, so b ends up being 8. Moving to the hundredths, I realize I need to solve for e, which also becomes 8 after borrowing. Then, in the tenths column, d comes out to be 7 after some deduction and borrowing from units. Finally, I check the units, confirming c must be calculated to ensure the result is a 6, matching the target of 96,889.Calculating the perimeter of a triangle

I misread a decimal earlier, correcting my calculation to find that 405.678 - 308.789 equals 96.889. Now, for problem 114, I’m determining the perimeter of a triangle. One side is 11.2 cm, the second is 15.7 cm (11.2 + 4.5 cm), and the third is 10.4 cm (15.7 - 5.3 cm). Adding these sides together gives a perimeter of 37.3 cm. I’ll keep my answer concise and include all necessary parts.
