Answer:

• let's first get the percentage decrease:

$= { \rm{100\% - 25 \% }} \\ { \rm{ = 75\%}}$

• then multiply the percentage decrease with the mass given:

$= { \tt{75\% \times 140}} \\ \\ = { \tt{ \frac{75}{100} \times 140}} \\ \\ = { \underline{ \tt{ \: \: 105 \: g \: }}}$

To recognize that over outfits are a mix of a blue shirt and black slack, it would be twice many more to add $\frac{1}{2} \ and \ \frac{1}{3}$ . Add $\frac{1}{2} \ and \ \frac{1}{3}$ , and remove the chance for both the black slack shirt and outfit and are one of the six outfits:
