Are 27/4 and 32/3 equivalent fractions?
Blababa [14]

Answer:

no

Step-by-step explanation:

27/4 = 54/8 = 81/12 = 108/16

= 135/20 = 162/24 = 189/28 = 216/32

= 243/36 = 270/40 = 297/44 = 324/48

= 351/52 = 378/56 = 405/60 = 432/64

= 459/68 = 486/72 = 513/76 = 540/80

= 567/84 = 594/88 = 621/92 = 648/96

= 675/100 = 702/104 = 729/108 = 756/112

= 783/116 = 810/120 = 837/124 = 864/128

= 891/132 = 918/136 = 945/140 = 972/144

= 999/148 = 1026/152 = 1053/156 = 1080/160

= 1107/164 = 1134/168 = 1161/172 = 1188/176

= 1215/180 = 1242/184 = 1269/188 = 1296/192

= 1323/196 = 1350/200 = 1377/204 = 1404/208

= 1431/212 = 1458/216 = 1485/220 = 1512/224

= 1539/228 = 1566/232 = 1593/236 = 1620/240

= 1647/244 = 1674/248 = 1701/252 = 1728/256

= 1755/260 = 1782/264 = 1809/268 = 1836/272

= 1863/276 = 1890/280 = 1917/284 = 1944/288

= 1971/292 = 1998/296 = 2025/300 = 2052/304

= 2079/308 = 2106/312 = 2133/316 = 2160/320

= 2187/324 = 2214/328 = 2241/332 = 2268/336

= 2295/340 = 2322/344 = 2349/348 = 2376/352

= 2403/356 = 2430/360 = 2457/364 = 2484/368

= 2511/372 = 2538/376 = 2565/380 = 2592/384

= 2619/388 = 2646/392 = 2673/396 = 2700/400

Chandler Heisinger buys a monthly metro card, which entitles him to unlimited subway travel in New York City, for $81 per month.
ANTONII [103]
Let r be the number of rides Chandler takes in a month. Then the cost with the MetroCard is still $81, but the cost without the MetroCard is 2r. So we can set up an equation representing what we want: "The cost with a MetroCard of r rides in a month is less than the cost without a MetroCard." In equations,
81\ \textless \ 2r \\ r\ \textgreater \ 81/2\ \textgreater \ 40 \\
r \geq 41
Thus, at a minimum, Chandler must take 41 rides for his MetroCard to be cheaper than not having it.
