Answer 1

Answer:

$2.65, $96 And $115

Step-by-step explanation:

1.(a)

$\huge{ \sf{ \green{ 20\% \: of \: \ \ 13.25}}} \\ \\ \huge{ \sf{ \green{ = \frac{ \pink{\cancel{ \green{20}}}}{ \pink{\cancel{ \green{100}_{ \: \orange{\cancel \green5}}}}} \times \orange{\cancel{ \green{ 13.25}}}}}} {}^{ \orange{ \sf \: \: 2.65}} \\ \\ \huge{ \sf{ \green{ = \orange{ \ 2.65 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }}}}$

(b)

$\huge{ \sf{ \green{15\% \: of \: \ 64 0}}} \\ \\ \huge{ \sf{ \green{ = \frac{ \blue{\cancel{ \green{15}}} {}^{ \: \: \blue3} }{ \blue{\cancel{ \green{10} }} \pink{\cancel \green0}}_{ \orange{ \cancel{\blue2}}} \times \orange{\cancel{ \green{64} }}\pink{\cancel \green0}}}}{}^{ \sf \: \orange{32}} \\ \\ \huge{ \sf{ \green{}}} \\ \\ \huge{ \sf \green = \orange{ \ 96 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }}$

2.

$\huge{ \sf{ \green{2500 \% \: of \: \ 4.60}}} \\ \\ \huge{ \sf{ \green{ = \frac{ \gray{ \cancel{ \green{25}}} \pink{ \cancel{ \green{00}}}}{1 \pink{ \cancel{ \green{00}}}} \times \frac{ \orange{ \cancel{ \green{460}}}^{ \: \orange{115}}}{ \gray{ \cancel\green{100}}}}}}_{ \sf \orange{ \cancel{\gray4}}} \\ \\ \huge{ \green{ \sf{ = \orange{ \ 115 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }}}}$
