we know there are 35 surfboards on the beach total, so the cheap answer is, we simply divide the total by the sum of the ratios, namely 35 by (1+4) and distribute accordingly.
[tex]\bf \cfrac{\textit{long boards}}{\textit{short boards}}\qquad 1:4\qquad \cfrac{1}{4}~\hspace{7em}\cfrac{1\cdot \frac{35}{1+4}}{4\cdot \frac{35}{1+4}}\implies \cfrac{1\cdot 7}{4\cdot 7}\implies \cfrac{7}{\blacktriangleright 28 \blacktriangleleft}[/tex]
Answer:
28
Step-by-step explanation:
sum the parts of the ratio 1 + 4 = 5
divide the number of surfboards by 5 to find one part of the ratio. = 7 ← 1 part of the ratio 4 parts = 4 × 7 = 28 ← number of short boards.
Hey man or girl, i'm sorry if this is incorrect. but if it is correct pls give me Brainliest.
