PROBLEM SOLVING
B. Solve the following problems. Write the answer with complete label.
1. Loree has a 34 m of T'boli cloth. She used 2/3 m for placement. What part of T'boli cloth was left?
[tex]\bold{Given}[/tex]: 34m of T'boli cloth, 2/3m used
[tex]\bold{Required}[/tex]: Part of T'boli cloth that was left
[tex]\bold{Solution}[/tex]:
Subtract the number of T'boli cloth Loree has and the part of the cloth that she used.
[tex] \implies \sf{ \red{ \bold34} - \bold{ \blue {\frac{2}{3} }}} \\ \\ \implies\frac{102 - 2}{3} \\ \\ \: \implies{\frac{100}{3}} \\ \\ \implies \: \sf \frac{100}{3} \: \: or \: \:{ \boxed{{ \bold{ \large{ \red{ 33 {\frac{1}{2} }}}}}}}[/tex]
Loree has 33 1/2m T'boli cloth left
2. Marvin bought a cake at bakery shop. She divided the cake into 10 equal parts. They ate 3/10 and left the rest on the refrigerator. What part of the cake were left?
[tex]\bold{Given}[/tex]: A cake that has been divided into 10 equal parts and the 3/10 part they'd ate.
[tex]\bold{Required}[/tex]: Part of the cake left
[tex]\bold{Solution}[/tex]:
Subract the cake that has been bought by the 3/10 part that has been eaten.
[tex] \implies{ \sf { \bold{ \large{1 - \frac{3}{10} }}}} \\ \\ \implies {\bold {\large{\frac{10 - 3}{10} }}} \\ \\ \implies \: {\bold {\blue {\large{ \frac{7}{10} }}}}[/tex]
Marvin has 7/11 cake left
3. Crisel has 2/8 meter of ribbon while Jeslyn has 3/8 meter longer to Crisel. How many meters of lace do girls have together?
[tex]\bold{Given}[/tex]:
Crisel- 2/8
Jeslyn- 2/8 + 3/8
All in all 2/8 + 2/8 + 3/8
Simply, 2(2/8) + 3/8
[tex]\bold{Required}[/tex]: Meters of lace the girls have together
[tex]\bold{Solution}[/tex]:
[tex] \implies {\bold{ \large{2 \times \frac{2}{8} + \frac{3}{8} }}} \\ \\ \implies {\bold{ \large{2 \times \blue{\frac{1}{4} }+ \frac{3}{8} }}} \\ \\ \implies \frac{1} \blue{2} + \frac{3}{8} \\ \\ \implies \large{ \bold {{ \boxed{ \frac{7}{8} }}}}[/tex]
They have 7/8 meter of ribbon together.
Hope this helps!
