Step-by-step explanation:

$\red{\underline{\underline{Question:-}}}$

A student measures the mass of an object A to be 50.3 grams and measures object B to be 200.24 grams. They then report the combined mass to be 251 grams. Are they correct? Why or why not?

$\red{\underline{\underline{Solution:-}}}$

The mass of an object A is 50.3 grams

The mass of an object B is 200.54 grams

The combined mass of object A and B is 251 grams

$\bold{We,know\:that\:combined\:\:means\:\:total\:\:weight\:\:of\:\: object\:A\:and\:B}$

$\Rightarrow A + B$

$\Rightarrow 50.3+200.24$

$\Rightarrow 250.27g$

$\Rightarrow 250.27g \neq 251g$

No,the report they were given wrong because they total weight is 250.27g

but they given 251 grams
